Service function chain collaborative control system and method for industrial Internet applications

Abstract

The invention discloses a service function chain collaborative control system and method for industrial Internet applications. The present invention includes an SFC policy controller, an SDN controller and an NFV controller; the network traffic in the system forms a network function service chain after passing through a series of network service function points in accordance with the established sequence required by the business logic, and each SFC policy control Each device contains a network function service chain; the SFC policy controller realizes the calculation and arrangement of the network service function chain; the SDN controller is responsible for configuring the underlying network devices through the southbound interface protocol, and diverting the data packets to the network service in the SFC Function point; the network service function runs on the virtual machine VM in the physical server. The system refers to this kind of virtualized network service function as NFV, and the NFV controller manages NFV through VM. The invention combines the IPv6 segment routing with the service function chain, and designs the system, which is an indispensable important technology for the future network.

Description

technical field [0001] The invention belongs to the technical field of network communication, and in particular relates to a service function chain coordination control system and method for industrial Internet applications. Background technique [0002] The large-scale popularization of the Internet enables people to enjoy corresponding services according to their own needs. These services are all provided by network operators, but most traditional networks currently use static business models, which makes it difficult for network operators to cope with the impact of a large amount of traffic. Especially in recent years, the explosive growth of the number of services and the demand for different types of service functions have made the traditional network even more overwhelmed. Service Function Chaining (SFC) is a technology used to flexibly manage specific services and flow control. It can classify traffic according to service requirements and guide traffic through approp...

Problems solved by technology

Among them, SR-MPLS is based on a distributed architecture and can be divided into LDP and RSVP-TE. At present, it has been used in some service providers, but it still uses the MPLS data plane, and the layering of the label stack is complicated, making it difficult to program the network. operation, poor scalability
